The defining event best describes what happened. - [Landing-landing roll: Landing gear not configured](https://openairdocs.org/ntsb-events/095) (defining event); cases with it: [Short Bros SD-360-300, 1 case](https://openairdocs.org/ntsb-events/095/sequence.md?model=8100610), [All aircraft, 584 cases](https://openairdocs.org/ntsb-events/095/sequence.md) ## Analysis The check pilot reported that, the pilot being evaluated was performing a simulated critical engine failure approach to a local airport. During the visual approach, everything seemed normal until touchdown when both pilots realized that the landing gear had not been extended. The airplane slid to a stop on the runway substantially damaging the lower fuselage. The check pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N970AA](https://openairdocs.org/aircraft/N970AA), registered now, S/N 3737, built 1988 (OpenAirDocs) - Reported make and model: SHORT BROS SD-360-300 - Registry model: [Short Bros SD-360-300](https://openairdocs.org/model/short-bros-sd-360-300) (registry code 8100610) (OpenAirDocs) - Registry engine: [Pratt & Whitney Canada PT6A-67R](https://openairdocs.org/engine/pratt-whitney-canada-pt6a-67r) (registry code 52208, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: 3737 - Year built: 1988 - Airframe hours: 24393.6 - Engines: Pratt & Whitney PT6A-67R turbo prop; Pratt & Whitney PT6A-67R turbo prop - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: ACC Integrated Services Inc - Registered owner: ACC Integrated Services Inc - Airworthiness certificate: Standard, Transport - Last inspection: AAIP, June 13, 2021 - Departed: KVGT, Las Vegas, NV - Destination: Same as departure - Flight plan: Company VFR - Airport: LAS, Harry Reid Intl, runway 08R/26L, 10,526 × 150 ft, concrete - Equipment: ADS-B, Electronic flight bag or handheld device, Stall warning system ## Flight crew As NTSB recorded them.
